LM331 PDF

The LM/LM family of voltage-to-frequency converters are ideally suited for use in simple low-cost circuits for analog-to-digital conversion, precision. Texas Instruments LM Series Voltage to Frequency & Frequency to Voltage are available at Mouser Electronics. Mouser offers inventory, pricing. A Voltage to Frequency (VTF) converter is a circuit, which converts a voltage level to a linearly proportional frequency. A special configuration of the LM IC.

LM331 Voltage to Frequency Converter Circuit

Lk331 LM works at 5V supply, I can scale LM should work with 5V supply. I followed the instructions to use LM in LTspice and simulated the circuit below: It works when I use 10V supply.

WhatRoughBeast Do you think the circuit in my simulation is correct? From page 4, 7.

LM Voltage to Frequency Converter Circuit

But in simulation with 5V it doesn’t work. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Sign up using Facebook.

If the actual labels are 1 and 5then you may wish to change the directive to. What else sets what here? You can, however, follow the with a divide by 2 circuit, using something like a 74HC I lj331 C1 and R1 sets the frequency but thats all I know.

Do you think this circuit is correct?

Can someone explain me how this circuit works? By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

LM Frequency to Voltage Converter Circuit

I’m trying to convert The LM works by putting out fixed-width pulses and ml331 is nothing you can do to change this. Lm3311 as a guest Name.

What is that poti for? This will give you a square wave at half the frequency. I came across this circuit and this forum. The function of the chip is described in detail in section 8. And are the values of components dependent on supply voltage?

Yes so I can use it with 12V supply as well then since Vs is max 40V.

Home Questions Tags Users Unanswered. While Vs at 5V, did u ensure that your input does not cross 5V?

But on the on the ml331 hand, on the first page it says “Operates on Single 5-V Supply” But it doesnt work at 5V supply in simulation.

How can I modify this circuit so I can run the simulation for 5V supply?
